Help with shuffling a playlists and my screw up

[AlexAkde]

Hey ya, tried to do a shuffle of a play list, and I followed this guide, https://www.dragonblogger.com/how-to-randomize-your-spotify-playlist-tracks/ Unfortunately it seems a bit outdated and you cant paste the new order. Is there any way for me to do this anymore, or is my playlist now gone? Help very much appreciated, I spent a lot of time on that playlist. I've still got the new order saved
